Abstract
The crane comprises a mast (6), mounted on a chassis (1, 3), and a distributor jib (7) composed of successive elements (14, 15, 16) articulated on one another about horizontal axes (24, 29), the first jib element (14) being articulated about a horizontal axis (18) on the top of the mast (6). The first jib element (14) and, if appropriate, the following element (15) can be brought into a substantially vertical position in alignment with the erected mast (6), so as to increase the height of the mast. All the jib elements (14, 15, 16) comprise a rolling track (17) for a carriage (32), and these elements can be used in various positions (B, F). A crane with modifiable configuration is thus obtained.
